Why should I use MSW for API mocking according to these patterns?

MSW mocks at the network level rather than mocking global fetch, providing a more realistic testing environment that catches more bugs and handles HTTP scenarios better.

Does it cover Next.js Server Components?

Yes, it includes guidance on testing server components at the integration level and through client-side wrappers for visual testing.

What testing frameworks does this skill support?

It provides comprehensive patterns and setup guides for Vitest, React Testing Library, Playwright, and Mock Service Worker (MSW).

What is the recommended query priority for testing components?

The skill prioritizes accessible queries like getByRole and getByLabelText to ensure your application is accessible to screen readers and resilient to implementation changes.
